Prompt Gamma Activation Analysis (PGAA) is based on the detection and analysis of gamma rays induced by neutron capture. This versatile nuclear analytical technique started propagating after the 1990s not just because of the difficulties of the spectrum evaluation, but also due to the lack of the proper analytical database. The first comprehensive spectroscopy database with the ambition of...
Developing nuclear fusion as a viable energy source requires demonstrating sustained plasma conditions and validating associated technologies, such as tritium breeding, as well as qualifying structural materials under extreme conditions. Future fusion reactors will operate in an intense neutron environment dominated by 14.1 MeV neutrons from deuterium-tritium reactions. These high-energy...
Achieving tritium self-sustainment in the breeding blanket will require a form of breeder within the engineering design of the machine which must produce an acceptable ratio of tritium to fusion neutrons to allow for a closed fuel cycle, with surplus to start up subsequent power plants. The design of the breeder and associated tritium plant must be maintainable and must be demonstrably safe...
Tungsten (W) is considered as a promising plasma-facing material for future fusion reactors. W components will be subjected to an intense flux of 14 MeV neutrons. This will result in creation of radiation defects, production of H, He and transmutation elements. Radiation defects can trap the tritium fuel, posing safety and economic concerns.
MeV heavy ion irradiation is widely used for...
